PETER MINEA, OF ST. PAUL, MINNESOTA.

SPECIFIGATION forming part of Letters Patent No.32l,995, dated July14,1885.

Application filed March 3, 1886.

T0 aZZ whom it may concern.-

Be it known that I, PETER h/IINEA, a citizen of the United States, and aresident of St. Paul, in the county of Ramsey, and in the State ofMinnesota, have invented certain new and useful Improvements in Vises,of which the following is a specification.

Figure 1 is a perspective view of the vise complete. Fig. 2 is aperspective front View, and Fig. 3 is a perspective rear view, of one ofthe removable jaws detached. Fig. 4 is a perspective front view, andFigs. 5 and 6 are perspective rear views,of one of the cheekplates, Fig.4: showing the construction of the face of the plate, Fig. 5 showing theconstruction of the rear of the plate viewed from above, and Fig. 6showing the construction of the plate viewed from below at the rear.Figs. 7, 8, and 9 are detached perspective views of the removable jaws,showing the various forms in which they will be constructed. Fig. 10is asectional side view of the upper parts of the vise without the removablejaws.

A A are the two main jaws of the vise, having the usual screw, B,hand-lever B and parallel cross-bars O O, in the ordinary manner.

Attached to the inner face of the upper part of each of the jaws A A aremetal cheek-plates D, with their upper parts projecting over their lowerparts, as shown, leaving recesses or depressions a in each. A slot, 1),is formed through each cheek-plate, as shown in Figs. 4:, 5, and 6, andthe faces of the slots within the depressed parts a are covered withcurved hoods d, the slots and hoods thus forming sockets adapted toreceive the tapering points 0 of the legs of auxiliary jaws orcheek-plate E.

By this means the auxiliary jaws may be inserted or removed at pleasureby merely lifting them upward.

The legs 6 are shown with offsets, so that the points e may be insertedinto the sockets at the backs of the depressions a, and with the rearsof the jaws E resting against the faces of the cheek-plates D, so thatwhen the vise is in use the pressure will be borne by the bodies of theauxiliary jaws resting against the faces of the cheeks D, which in (Nomodel.)

turn rest against the main jaws of the vise, so that the pressure willin no case be borne by the legs e or points 6.

The depressions a in the cheek-plates D are a very important feature ofmy invention, as they enable'nie to support the auxiliary jaws, with thehoods d, in lines back of the upper parts of the faces of the cheeks D,so that when the auxiliary jaws are removed no part of the cheek-platesprojects beyond their upper parts, to enable the vise to be used as anordinary vise when the auxiliary jaws are removed. This will be moreclearly understood by reference to Fig. 10, which shows the vise withthe auxiliary jaws removed.

Each of the jaws A A will be provided with one of the cheek-plates D, sothat the auxiliary jaw may be attached. to either cheek; or, ifrequired, two of the auxiliary jaws may be used, as shown in Figs. 7 and8, which represent a concave jaw and a convex jaw adapted to hold curvedpieces between them.

It is evident that any desired form of jaw may be used, and in practiceI intend to furnish with each set of check-plates D a series ofauxiliary jaws adapted to the varied forms of the work to be held.

In Figs. 1, 2, and 3 the auxiliary jaw E is formed with an angular back,and adapted to turn upon the leg e, so that the face of the jaw willadapt itself to the form of the work being held in the vise. This formofjaw will hold with an equal pressure all angles within the radius ofits movement.

In Fig. 9 an auxiliary jaw is shown, with the inclination at rightangles to the inclination of the jaw shown in Figs. 1, 2, and 3.

This invention may be attached to nearly every form of vise; but it willgenerally be used on the wooden vises used by carpenters, wagon-makers,patternunakers, &c.

The invention may be applied to old vises, or attached to and sold withnew vises, as pre ferred. 4
